It will look pretty much like any common Mdl 15 but will probably not have the reverse / back tack feature found on the later ones.

Joe, do you know the year the back tack feature was introduced? I am looking at a model 15 from (supposedly) 1939. Another member thought it would have the reverse feature, but then another source said that feature wasn't introduced until 1950. Not sure where to get a conclusive answer on this! It would be cool to have that feature on a model 15 treadle.
